Abstract:
(EN) Provided in the present invention are a graphene-loaded silver ferrite (Ag-MFe2O4) nano composite material, and a preparation method and an application thereof, the nano composite material being a composite of graphene-loaded silver ferrite heterogeneous nano particles. The preparation method may use a process of directly loading the silver ferrite hetereogenous nano particles onto graphene, or may also use a process of first loading the particles onto graphene oxide and then reducing same. As an electrocatalyst, the graphene-loaded silver ferrite nano composite material has good stability, resistance to methanol toxicity, high electrical conductivity and high catalytic activity; the preparation method thereof is simple and low cost, the reaction conditions are easily controlled, and the obtained material has a uniform morphology, good dispersibility, and can easily be expanded to large scale production.
(FR) La présente invention concerne un matériau nanocomposite à base de ferrite d'argent chargée de graphène (Ag-MFe2O4), un procédé de préparation et une application de celui-ci, le matériau nanocomposite étant un composite de nanoparticules hétérogènes de ferrite d'argent chargées de graphène. Le procédé de préparation peut utiliser un procédé de chargement direct des nanoparticules hetereogènes de ferrite d'argent sur du graphène, ou peut également utiliser un procédé de chargement préalable des particules sur de l'oxyde de graphène, puis une réduction de celui-ci. En tant qu'électrocatalyseur, le matériau nanocomposite de ferrite d'argent chargé de graphène a une bonne stabilité, une résistance à la toxicité du méthanol, une conductivité électrique élevée et une activité catalytique élevée ; le procédé de préparation de celui-ci est simple et peu coûteux, les conditions de réaction sont facilement contrôlées, et le matériau obtenu présente une morphologie uniforme, une bonne dispersibilité, et peut facilement être étendu à une production à grande échelle.
(ZH) 本发明提供了一种石墨烯负载银-铁氧体(Ag-MFe2O4)纳米复合材料及其制备方法和应用,所述纳米复合材料是由石墨烯负载银-铁氧体异质纳米颗粒复合而成。其制备方法既可以采用银-铁氧体异质纳米颗粒直接负载在石墨烯上的工艺,也可以采用先将颗粒负载在氧化石墨烯上再还原的工艺。石墨烯负载银-铁氧体纳米复合材料作为电催化剂稳定性好、耐甲醇毒性、导电性和催化活性高,其制备工艺简单、成本较低,反应条件易控,所得材料形貌均一,分散性好,易于扩大规模生产。
